电机连着主轴，主轴带个增量式旋转编码器，已知编码器为1600线，主轴直径为150mm, 主轴为变速转动，变速后面伸出来的轴同样是150MM后面带了一个转盘为1M。     求1、主轴的当前时刻转速是多少？2、编码器一个脉冲所对应的长度是多少？3、当长度为2000mm时，编码器输出多少个脉冲？        如果所列的已知条件不充分，请假设已知条件。     如何计算?请列出公式！
答：1）这个就是需要你记主轴在单位时间内的脉冲数就是电机当前时刻的转速。实际上这个也不需要什么计算，你只要在OB35中读脉冲数，比如OB35设置1000ms，读到的脉冲数就是电机转速（rpm/S）。按常用计量单位你乘60，即rpm/min。
2）因为编码器直接连接在电机输出轴上面，则电机旋转1周，实际编码器输出1600个脉冲。这样当电机转动1mm，则编码器的脉冲数为电机周长/1周脉冲数。150*3.14/1600=0.294375mm，即电机驱动编码器走1个脉冲，而实际电机转动了0.294375mm。
3）转盘转动2000mm，则编码器实际发出的脉冲数为2000/0.294375=6794。
